A do-it-yourselfer by the name of technocrat (possibly not their real name) has created this fantastic t-shirt with a working version of the YouTube loading animation that everyone has patiently spent time staring at.

Using an Arduino, a 9-volt battery, and eight ping-pong balls with a white LED inserted into each one, the ring of dots lights up in sequence, endlessly chasing its tail waiting for a non-existant video to load. A giant F5 refresh button would have really completed the costume, though, since that's everyone's secret weapon for getting a YouTube clip to finally load. [Hack a Day via Technabob]
